Change the line:

if(access == '') {

To:

if(access == null) {

This is the default return value of the localStorage.getItem() method for an unpopulated key.

You're doing it wrong. in this if

 if(access == '') {
    var d = new Date();
    console.log(d);
    var time = localStorage.setItem('firstAccess', JSON.stringify(d));
    setTimer(time);
  }

Switch to this

 if(!access) {
    var d = new Date();
    console.log(d);
    localStorage.setItem('firstAccess', JSON.stringify(d));
    var time = localStorage.firstAccess
    setTimer(time);
  }
